Real time radiation readings around Fukushima Prefecture can be found on NRA’s website here.
A couple of the cities near the plant have no stations but there is a wide variety around the region.
We have found many of these to be over the .5 uSv/h level used for evacuation at Chernobyl.NRA’s radiation database can be accessed herehttp://radioactivity.nsr.go.jp/map/ja/download.html
